How late can you cancel a United flight? The United Airlines cancellation policy varies based on your ticket type and fare rules. Typically, for most standard tickets, you can cancel within 24 hours of booking, provided it's at least seven days before departure, without incurring fees. Beyond 24 hours, fees and eligibility for refunds or credits depend on the fare class and the remaining time until departure. Some tickets, like Basic Economy, may be non-refundable. To cancel, contact United Airlines at 800-864-8331 or 1-844-902-4930 (OTA-Skip Waiting). To learn more about How late you can cancel a United flight, read a blog on the Airlines Pet Policy website.
